WILLIAM MANN, OE NEWCASTLE, PENNSYLVANIA.

Letters Patent No. 101,750, dated April l2, 1870.

IMPROVE!) MACHINE IEOR` CORRUGATING- SHEET METAL.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom Iit may concern Be it known that I, WILLIAM MANN, of Newcastle, in the county of Lawrence and-State of Pennsylvania, have invented certain new and useful Improvements in Machines for Corrugatin g Sheet Metal;

and I do hereby declare that the following is a full,

clear, and exact description thereof, reference being had to the accompanying drawings and to the letter of reference marked thereon, which form a part of this specification. 1

'Ih nature of iny invention consists in the construction ot a machine whereby sheet metal can be .ally therewith, forming bealings for a bed-plate, B, of.

suitable material, itsy upper face heilig curved and formed vto the required shape of corrugated sheet metals, and having underneath slides B1, which rest in the before-named grooves A'. Said plate B is furthermore furnished with an ordinary geared rack, B2, running longitudinally with and 'being between said slides Bl.

Engaging the teeth of said rack B2 is an ordinary geared wheel, G, aiiixed to a shaft, C', laying underneath and-transversely with said frame A, to which it is attached by means ot' ordinary bearings in which said shaft Clrevolves.

f Ihe said gear-wheel C engages the teeth of an ordinary gear-wheel, D, ai'lixed to a shaft, D, revolving in suitable bearings atiixed to said iiame A, the

j outer extremity of'said shaft I)l heilig provided with 'au ordinary gear-wheel, D2, which fits into the teeth of au ordinary gear-wheel, E, atiixed to a drivingshaft, El, parallel to said shaft D1, and revolving in suitable bearings attached to said i'ame A, said shaft E* being provided at its outer extremity with the ordinary driving-pulleys E", similar in construction and adaptation tothose used on an ordinary metal planing-machine.

'Ihe before-named shaft C is provided at vits outer extremity with a gear-wheel, F, which engages in the teeth of two ordinary gear-wheels, G and G, aixed to the extremities of two rolls H H, said rolls being above audlaying transversely with said bed-plate B.

From the said' frame A arc bearings H in which said rolls revolve, the shape of said rolls H H correspending with the curved form of the upper portion of the said plate B, and so arranged that there will be a slight partition between them.

If required, any ordinary screw or other lifting-gear can be attached to said rolls H H, by which they can 'be raised or depressed to any required point.

The table or plate B and the ii-ame A are provided with the ordinary catches and levers usuallyin use on metal planingmachines, by the manipulation of which the belt which drives the machine is thrown on and otf the several pulleys i, the whole being so arranged that, by the revolution of the driving-shaft El, the

whole of the described machinery is set'iu motion.

Sheet metal being placed on the bed-plate B, in its forward motion it carries the metal to the rolls H, by whose act-ion it is pressed down into the curves of the bed-plate, and, havingpassed through the rolls, is a completed plate.

By the operation of the catches and levers operating on the driving-belt, the motion of the table B is reversed and returns to its original position, and is ready for the manipulation of'4 another plate.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the lplate B and the rolls H H with the gearing described, when the parts are coustructed as and for the purpose set forth.

In testimony that I claim the foregoing as my own, I atiix my signature in presence of two witnesses.

Witnesses: TILLIAM MANN.
